Description of drawings
The process flow diagram of a kind of high-end disk array management method that Fig. 1 provides for embodiments of the invention one;
The structural drawing of a kind of high-end disk array management devices that Fig. 2 provides for embodiments of the invention two.
Embodiment
In order to solve the problem of the loss of data in the high-end disk array buffer memory under the emergency case, embodiments of the invention provide a kind of high-end disk array management method, this method is by timely initiation controller refreshing buffer memory, data in the current cache are in time write hard disk, thereby guaranteed data consistency, realized the disaster tolerance function of high-end disk array.
At first in conjunction with the accompanying drawings, embodiments of the invention one are described.
The embodiment of the invention one provides a kind of high-end disk array data managing method, in the embodiment of the invention, is that example describes with eight controller high-end disk arrays.In 8 controllers of this high-end disk array, select two controllers of preserving as data under the emergency case such as control outage.Use this method to high-end disk array, especially the flow process to the management of high-end disk array comprises as shown in Figure 1 under the emergency case:
Each disk working condition in step 101, the first monitoring control devices high-end disk array;
In the embodiments of the invention, related high-end disk array all uses UPS.Have the working condition of the controller of managerial ability by the whole high-end disk array of SNMP module monitors of UPS in the high-end disk array, in the embodiment of the invention, the controller with managerial ability has two, is respectively controller 0 and controller 1.Concrete, under the civil power power-down conditions, the SNMP module of UPS sends trap information to controller 0 and controller 1.
In this step, when controller 0 and controller 1 receive trap information, start the snmptrapd service, specify the power down process script that presets, notify other each controller flush buffers, and stop related service.Concrete, described first controller starts the power down process script, and other controllers send the UPS warning information in described high-end disk array, and trap information has been received in expression.The mode that sends signal writes a specific alarm signal for the file below fixed route.First controller is notified each the controller flush buffers data in the described high-end disk array, with the described data cached corresponding hard disk that writes in the described high-end disk array, stops service.
In addition, because the controller that exists a plurality of (two and more than) to have managerial ability, a plurality of controllers detect opportunity of trap information may be different.Specifically comprise following two kinds of situations:
1, when two controllers had been received the trap information of SNMP Trap transmission simultaneously, controller 1 had received the warning information that controller 0 sends over again in a second after receiving the UPS warning information, and then controller 1 is not carried out relevant action; Controller 0 is notified each controller flush buffers, the operation that stops to serve;
2, controller 1 has at first been received the warning information that SNMP Trap sends; Controller 1 does not receive the warning information that controller 0 sends in a second after receiving the UPS warning information, other each controller flush buffers of its exercise notice then, the operation that stops to serve.
Receiving warning message later at first to other controller transmission signal, warning information has been received in expression.The mode that sends signal writes a specific alarm signal for the file below fixed route.
Below in conjunction with accompanying drawing, embodiments of the invention two are described.
Embodiments of the invention two provide a kind of high-end disk array data administrator, and high-end disk array uses UPS, and the structure of this device comprises as shown in Figure 2:
Monitoring modular 201 is used for monitoring each disk working condition of high-end disk array;
Preferably, described administration module 202 also is used for refreshing corresponding hard disk cache, and stopping service when described monitoring modular 201 receives the UPS warning information that the controller of described high-end disk array sends.
Below embodiments of the invention three are described.
The embodiment of the invention provides a kind of high-end disk array data management system, comprises first controller and second controller at least;
Described first controller is used for monitoring each disk working condition of high-end disk array, and when detecting outage, notifies the described second controller flush buffers, stops service;
Described second controller is used for when receiving the notice of described first controller, refreshes corresponding hard disk cache, and stops service, and described notice is specially the UPS warning information.
Below, embodiments of the invention four are described.
The embodiment of the invention provides a kind of high-end disk array management system, and this system mainly comprises the SNMP module of three module: UPS, controller monitoring module, trap signal processing module.
The SNMP module of UPS: mainly carry out the civil power detection of power loss, issue wrong trap signal in the situation of power down.
Controller monitoring module: open the snmptrapd service after two controllers start simultaneously, monitor the udp162 port in real time.
Trap signal processing module: after receiving signal,, dispose electric signal, refresh eight controller caches simultaneously as long as two controllers have a duty.
High-end disk array data managing method, device and system that embodiments of the invention provide, high-end disk array uses UPS, each disk working condition in the first monitoring control devices high-end disk array; When detecting outage, described first controller is notified other controller flush buffers in the described high-end disk array, stops service.Realized the timely response of outage time control system device, deposited the data of storing in the current cache in hard disk, effectively prevented loss of data, solved the problem of the loss of data in the high-end disk array buffer memory under the emergency case by flush buffers.
When not increasing cost, realize the redundant manipulator monitoring, improved and refresh the reliability that high-end disk array reads and writes data in real time, realized the trap intelligent monitoring simultaneously, under the situation that does not reduce system performance, as much as possible farthest protected user benefit.
